Predecessor to the Japanese intelligence

Special Higher Police(特別高等警察 Tokubetsu Kōtō Keisatsu?), often shortened toTokkō(特高 Tokkō?) was a police force established in 1911 in Japan, specifically to investigate and control political groups and ideologies deemed to be a threat to public order

This organization was shut down when the World War II ended, though their members were rehired to counter the communist in 1950s, which was the origin of Japanese intelligence division of the police department.
